Diana A. Antonosyan, Alexander S. Solntsev, Andrey A. Sukhorukov, Yuri S. Kivshar · 2013
We demonstrate that generation and quantum walks of biphotons with non-classical spatial correlations in nonlinear waveguide arrays is tolerant to losses for different pump regimes, and suggest quick loss characterization approach based on nonlinear spectroscopy.
